X+3+2x+1+3x-4=180(the sum of all angles of a triangle is always 180 )
so 6x=180
x=30
x+3=33
2x+1=61
3x-4=86 are the required anglea
So,
All of the options look so ridiculous that I will not bother discussing why they are not equivalent.
However, one option works.
"2 + 13x, because (19x - 6x) + 2 = 13x + 2 = 2 + 13x"
If you simplify the original expression, you will get 13x + 2. And the only option that is the closest is 2 + 13x, which is the same as 13x + 2, according to the Commutative Property of Addition.
Answer:
I think it's 900
